- Removed PersistentPerson and PersistentPersonPlayer.
- PlayableCharacter now references WiseguysUser instead of PersistentPerson.
- The new WorldEntityUser handles the character/spectator spawn & reference stuff that PersistentPerson used to handle.
- Removed BuildingUnitOccupiers as we no longer use the building takeover stuff, and it should be made game-mode-specific now if we need it back.
- Stuck GangMember in WiseguysUser for now to make things compile, but probably want to replace it entirely with an IPlayerComponent gang member equivalent?
